METHOD AND SYSTEM FOR CHANGE DETECTION USING AR OVERLAYS

One embodiment can provide a system for detecting a difference between a physical object and a reference model corresponding to the physical object. During operation, the system obtains a real-world image of the physical object and generates an augmented reality (AR) image by projecting a three-dimensional overlay generated from the reference model onto the physical object in the real-world image. While generating the AR image, the system aligns a pose of the reference model to a pose of the physical object. The system can detect the difference between the physical object and the reference model based on the generated AR image and the real-world image.
